Meanwhile, the Reds sold and loaned a number of players, as manager Jurgen Klopp looked to further refine his squad, as they push on in their efforts to win their first league title since 1990. Here's a look at how all the players who left Liverpool over the summer, on loan or transfer, are getting on so far this season.
The Gers battled hard with Leeds United to get their man, but he's not had the best start to life at Ibrox. He suffered a hamstring injury on his debut, and hasn't really impressed since returning to the side.
After impressing on a loan spell with the south coast side last season, they stumped up 18m to land him in the summer. He's been banging the goals in, and scored five in four games earlier in the campaign.
He's caught the attention of a number of other top clubs with his performances at Reading, where he's been dazzling the Championship with his audacious skills.
He's still a free agent, but there are whispers of Scottish Premiership side Hibernian looking to snap him up.
He's now with Bulgarian side Arda Khardzali, who are sixth in the nation's top tier.
Looking to reignite his injury-plagued career, the ex-England striker got his new start in Turkey off to a flyer, with two goals and two assists in as many games. He is, however, now injured again.
He's scored four goals from the wing for Rangers, including the winner in a 1-0 Europa League win over Feyenoord.
Another bright hope for the future, snapping up the Wales international was a real coup for Oxford. He's not been sensational as of yet, but his side are looking strong contenders for a play-off spot.
It never quite worked out for Moreno at Anfield, and there was no chance he'd be getting a game over Andy Robertson any time soon. His new club are in mid-table, and he's been used sparingly.
Now on his third consecutive loan spell away from the Reds, Grujic is continuing to develop into a quality midfielder. He's been one of his side's best players this season.
No longer content to warm the bench, the goalkeeper is now back in Belgium and playing Champions League football. His heroics helped his side earn a 2-2 draw with Real Madrid.
After excelling under Frank Lampard at Derby County last season, Wilson has made the step up to the Premier League level with aplomb. He's netted four times thus far.
The Nigeria youth international current club are struggling in the German top tier, and he's only made one start for them in a particularly tricky loan spell.
